Can You Paint a Primed Wrought Iron Fence With Exterior Latex Paint?

Metal Primer

• Before you paint a wrought iron fence, verify the correct primer covers the surface. A metal primer contains properties to prevent rust development. If there is any rust showing through the primer, you need to use a wire brush to scrape off the rusted area and re-prime the fence. When existing rust remains on the metal fence, it will eventually show through the primer and cause discoloration.

Latex Paints

• Latex paints dry quickly and clean up easily due to the water that creates the thin paint. They come in various finishes including flat, gloss and stains and contain specific properties for interior and exterior use. While some exterior latex paints are not appropriate for painting metals, as the water in the paint may contribute to rust through oxidation, you can use an acrylic or rubber-based latex paint on an outdoor wrought iron fence.

Acrylic Latex Paints

• According to leading paint manufacturer Benjamin Moore, provided the metal surface does have on a coat of primer, you can use an exterior acrylic latex paint on the metal. A wrought iron fence must withstand extreme environmental elements. Choose an exterior paint with acrylic exterior latex. Tthe artificial polymers it contains seal the metal and protect the fence from rust-inducing rain or ice.

Oil-Based Paints

• Oil-based paints contain bonding agents that help the paint adhere well to metals. The adhesion in this paint creates a barrier that prevents rust formation. These paints are, however, more difficult to apply due to the thicker consistency, produce strong odors and cannot cover a water-based primer.
